At standard temperature and pressure, carbon dioxide has a density of 1.98 kg/m3. What volume does 1.70 kg of carbon dioxide occ
1 answer:
Answer:
<h2>volume= 0.85m^3</h2>Explanation:
<em>The density of a substance is defined as the mass per unit volume of the substance, the unit is in kg/m^3 and it is represented by the greek letter rho</em>
Step one:
given data
we are told that the density of Co2= 1.98 kg/m3
and the mass of Co2 is= 1.70 kg
we know the relation between mass, volume and density is
make volume subject of formula we have
substitute we have

Answer:
The apparent weight of the person as she pass the highest point is
Explanation:
From the question we are told that
The radius of the Ferris wheel is
The period of revolution is
The weight of the person is
Generally the speed of the wheel is mathematically represented as
substituting values
The apparent weight (the normal force exerted on her by the bench) at the highest point is mathematically evaluated as
Where m is the mass of the person which is mathematically evaluated as
substituting values
So
The question can be solved using conservation of linear momentum.
= 0.06kg and
= 0.03kg
Let the initial velocity of Marble A be , = 0.7m/s
Let the initial velocity of Marble B be, = 0m/s
Let the velocity of Marble A after collisiong , = -0,02m/s
Let the velocity of Marble B after collision be
From the conservation of linear momentum equation. We get,
Substituting the values we get,
(0.06)(0.7) + 0 = (0.06)(-0.02) + (0.03)
we get, = 1.44m/s
